I am an absolute beginner with Python and I am finding the following strange behavior in my program if I execute it using Python 3 instead using Python 2.

I will try to explain the situation in details.

I have these 2 versions of Python installed on my machine:

• Python 2.7.17
• Python 3.7.7

Then I have this script using Scapy:

I am an absolute beginner with Python (I came from Java) and I have the following doubt about the venv folder in my project.

So basically I have this project structure:

As you can see it contains the venv folder. Reading on the Python official documentation: https://docs.python.org/3/library/venv.html

I can read:

The venv module provides support for creating lightweight “virtual environments” with their own site directories, optionally isolated from system site directories. Each virtual environment has its own Python binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Python packages in its site directories.

So from what I can understand it means that, using venv, every project have its own venv folder containing:

1. The bin folder: it contains the Python interpreter binary (in this specific case Python 3.7).

2. The lib folder: containing the dependencies that I have installed using pip3 (infact I installed scapy and scapy_http via pip3)

This because my PyCharm IDE is set to use Python 3.7

If this reasoning is correct (I am asbolutly not sure) it means that when I run something like:
